To a'ZZ whom t may concern.'

Be it known that we, RALPH G. TAYLOR and CLAUS J. WERNER CLASEN, citizens of of America, and residents the United States of Davenport, Scott county, Iowa, have'in- 'vented a certain newv and, useful Improvement in Draft-Rigging, of which the fol-v lowingl is a specification;

y This invention relates to draft rigging. for

railway cars and particularly to a supporting structure v that will accommodate the standard type of draftgear as ordinarily applied to freight cars.

The main object, of the invention is to provide a draft rigging of improved construction for a car underframe having a single rolled beam center silll extending continuously from end sill toend sill and which will permit of the use of a. standard draftgear, such as the tandem spring type provided with the usual vertically disposed yoke.

Another object of the invention is to provide a. draft rigging for Iapplication 'to a continuously disposed single I beam center' sill in a manner to leave unencumbere'd the upper portion of the web and all of the upper ange by any part or.portion ofthe draft' rigging in thevicinity of its connection thereto.

These and Othepobjeas which will herein-' after appear, are attained bythe structure illustrated in the accompanying drawings,

in whichv Figure lis a side elevation, partly'in section, of the end of a car, provided with` a single I beam center sill and showing the 1mproved draft rigging applied to same. Fig. 2 i's a vertical cross section of a portion of '40 the 'car taken on line A-B of Fig. 1. Fig.

' 3 i's a pll n view of the end f asingle I beam center sill showing in dotted lines the manner of attaching the draft rigging thereto. Fig. 4 is a vertical cross section of the center sill and draft rigging taken on line of Fig. 3. Fig. 5 is a modification of the structure shown in Fig. 4. Fig. 6 is a plan View in longitudinal, horizontal section o f a s1r igle center sill draft rigging embodying this invention.

. Similar numerals refer to similar throughout the severalviews.

' Among the various elements of an M. C. B. standard draft rigging are the coupler parts A* 56 'shank or draw bar 3 the vertically disyoke-5. By a vertically disposed yoke -beam center `sill 1 is meant one as shown in Fig/1, that is, ex-

tending from .the rear end ofl the drawbar back over the top of springs, around the rear buliing block and passing forward vagain under the follower plates and springs to the draw b'ar to' which itis securely fastened'. Any draft rigging in which these'yokes pass along thesides of the followers and springs, or are horizontally `disposed are not considered standard but are known as specials.'

NOW t5h@'Ilflidlinfobject of this invention is' form of draftrigging -v y 70+? to apply a standardl to a single rolled .beamcenter sill, preferably-of I vcross section, that does not termithe follower plates and.

nate in thevicinity of the -body holsters of the car underframe, lbut a center sill that is made to extend continuously from end Sill to end sill. l

maintaining'the M. C. B. established center plate height anddistance, or height from'top ofi rail to center of coupler it would be a comparativelyv simple matter to attach -a standard draft rigging to theunderside of the center sill as has long been the practice in wood car construction, but in substituting.

a singleymetal vsill of` equal Carrying capacity for the old wood sills, a -beam of cog- -paratively great depth of section must employed, so deep. that in attaching the ctie.- Dler to the underside thelio'f urements could not be sill 2 at one end 4of the car to a similar end sill 'at the other end is coped or cut away by.. removing a portion of the webv and all ofthe lower flange for some distance back from each end as indicated bythe dotted line E, F, G -in Fig. 1.. Extending into the pocket thus formed isA the horizontally dis- .'If it were not for'the'necessity of aintained. Thev-I- which extends from end B. measposed draw-bar 3, to which is connected. b v

the. rivets 4, the vertically disposed drawvbar-yoke 5. This yoke is preferably made of a single piece, passing over the draft gear. bending .around therear end and returning underneath thereof. The filler block 6 is fitted tothe rear bent end of the yoke and riveted thereto as shown at 7 Intermediate the longitudinal length of the yoke and between the top and bottom members the block 8 is securely riveted thereto by the rivets The front and -rear followers 10, l()a and the intermediate followers 11, 11 extend transversely through thel "ei-ticall)v disposed draw-bar yoke 5.

The draft arms 12-12, one on each sido of the center sill web, forming a housing or Vsupporting structure for 'the draft gear mechanism and through which the bufling 'di vertical flanges 12a the walls of the draft arms, for the greater portion of their length,

j exte'ndllaterally a short distance and thence downwardly thus forming a passage-way for the lupper limb of the draw-bar .yoke 5. These walls againV extend laterally for another short distance and thence 'downr wardlv. terminating in the outwardly projecting flanges 12b, thus forming the housing proper forthe reception of the, draft gear mechanism. At the rearl end the walls of the draft arms are bent or brought in toward and closely embrace the web of the center sill to which they are securely riveted as shown at 12C. The flanges 12b lapa over and are riveted to the lower flange of the center sill. The side walls of the draft arms in the vicinity of the draft gear mechanism are recessed forming the stops4 or shoulders 12d 12e 1:2 1:2g`12h 1'2j 12k 121 for the followers 10--10a and 1111a to abut against. The stops 19e 12f 121' and 1*?.k ar'elimiting stops for the followers 11 and 11a to vguard the cushioning springs Z13-13a against crushing., These followers 11 and- 11d are -reciprocated longitudinally with the draw-bar yoke 5 in pulling'or buffing through1 their contactnvith the blockA 8 which is secured to the drawbar yoke by the vertical rivets 9 heretofore referred to. It is thus seenthat these draft arms assumel such shape when assembled to permit the use of a vertically disposed drawbar yoke and differs materially in this rei :spect from all draft riggings applied to'the web of a single centersill.

The forward ends 14 of the dra-ft arms eX-' tend beyond the end sill 2 to receive the striking plate 15. ln the lower part of the outer end the draw-bar carrier v16 is fitted and held in position bybolt 16a. The outer end of the vertical flange 12'rl is increased in height and terminates inthe laterally eX- tending flange 17 by which it is secured to the end sill 2. The draft gearing including the followers and springs are supported'by the usual carrier plates (not shown) bolted` to the underside of the "flanges 12b.

1n the structure shown in the drawings the draft rigging including the draft arms are in no manner connected to the body bolster 18 which ypasses through a suitable opening in the web of the center sill adj ac ent` the rear end of the dra-ft arms and is surrounded by the supporting gusset 19.l The draft' rigging is thus secured to the single center sill1 in a most substantial and workma'nlike manner and 1s so attached as to leavethe upper flange of the center sill unobstructed or unencumbered, free to receive the hinges of dump.l doors lor other devices as the occasion may require.y Fig. 5 shows.

a modification Iof these improved draft arms, by casting same in a single'piece and 4pro- -vilding the vertical flanges 20-20a also cast integral 'between which the web of the center sill is riveted. This is to be considered the ful'l equivalent of the device herein described and'in no manner departing from the spirit of this invention- That we claim as new is:

. 1.' 1n a tandem spring draft rigging, the combination with a draw-'bar land vertically disposed draw-bar yoke connected to said draw-bar, tandem'arranged springs, f ront,

rear and intermediate followers; 'a slngle' .2. In a tandem spring draft rigging, the

combinationwith a single, center sill having.

a vertically disposedweb and having the ends reduced vertically, a` draw-bar in line with the center sill, a vertically disposed draft yoke connected to the draw-bar and lying in the 'plane of the center si'll web, a pair of vertically disp'osed'devices connected to said yoke Iinthe plane of the center sill web, a spring' and a pair of followers arranged between said devices, a second spring and a pair of followers arranged between one of said devices and the endof the draw-bar, intermediate stops and end stops vertically disposed-and secured to the center sill and coperating with said followers.l

3. .A draft and buffing gear' comprising an I beam with the lower flange and a portion of its web y'removed for a distance at each end,

. cheek plates secured to opposite sides of the beam, a draw-bar, followers, a cushioning device in connection with the followers, and a vertically disposed yoke connecting the draw-bar with the'rear follower.
